Answer 1

This could be what you need. You need to enter your Google username and password in the $email and $passwd variables and to setup the autoloader or require ZF classes.

References: Zend_Gdata_ClientLogin and ClientLogin

// setup the autoloader first or require used classes
// using the example code in the example to get auth tokens
try {
    $client = Zend_Gdata_ClientLogin::getHttpClient($email, $passwd, 'xapi', $httpClient);
} catch (Zend_Gdata_App_CaptchaRequiredException $cre) {
    echo 'URL of CAPTCHA image: ' . $cre->getCaptchaUrl() . "\n";
    echo 'Token ID: ' . $cre->getCaptchaToken() . "\n";
} catch (Zend_Gdata_App_AuthException $ae) {
    echo 'Problem authenticating: ' . $ae->exception() . "\n";
}

// extract authentication tokens from response body
$ck_count = preg_match_all('/^(.+)=(.+)$/m', $client->getLastResponse()->getBody(), $cookies);

// build a new http client
$auth = new Zend_Http_Client('http://www.google.com/trends/viz?q=facebook&graph=all_csv&sa=N');

for ($i = 0; $i < $ck_count; $i++) {
    // authenticate it using the provided tokens as cookies
    $auth->setCookie($cookies[1][$i], $cookies[2][$i]);
}
// make the request and dump cvs data
Zend_Debug::dump($auth->request()->getBody());
